HINGE-JOINT FOR JEWELRY.

SPECIFICATION forming part of,, Letters Patent No. 354,458, datedDecember 14 1886.

Application filed February 2, 1886. Serial No. 190,598. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE BEcKER, of the city and county of Providence,and State of Rhode Island, have invented certain new and usefulImprovements in Hinge-Joints for Jewelry, of whichthe following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to the class of hingejoints which have thehiuge'leafpro vided with pintles to swing upon.

The object of my invention is to provide a joint especially adapted inthe construction of hingejoints in jewelry, and which is simple, strong,and Very durable.

To the above purposes my invention consists in a hingejoint having aleaf which is provided with oppositely-disposed fixed pintles, whichvibrate in slots formed in the bearing or cradle piece, and of thepeculiar stop and sleeve mounted on the leaf, and of othersubcombinations, all hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention,Figu re Arepresents abroad side view of my peculiarleafwith its pintles. Fig.8represents an under sideview of Fig. A. Fig.C represents a side view ofmy leaf mounted upon a sleeve. Fig. D represents an end view of Fig. C.Fig. E represents a top view of my cradle or bearing before beingfinally swaged and mounted upon a bar lying below and shown in portion.Fig.F represents an end view ofparts in Fig.E, with the parts in Fig. Dinverted and set down in the former. Fig. G represents Fig. F afterfinalswaging ofthc sides of the cradle or hearing. Fig. H representstheparts in Fig. G reduced and joined up with an ordinary breastpin. Fig. Irepresents a modified form of my joint attached to a breast-pin, shownin part. Fig. J represents a further modification of my peculiar leafand pintles. Fig. K represents a blank from which the leaf in Fig. J isswaged.

In the said drawings like numbers of reference designate like partsthroughout.

Referring to the drawings, theleaf 1 is. a flat body, approximately aninverted- U shape, and has upon its two broad sides the oppositelyfixedpintles 2, which are short cylindrical bodies. At the lower left-handcorner, Fig. A, the leaf 1 has a small stop, 3, and the sleeve 4 ismounted upon the lower edge, with one end abutting against the stop 3,which is designed to give a ready and accurate adjustment to said sleevewhen being set in position.

The

several parts 1, 2, and 3 are integral, being struck up from fiat blanksof material.

The cradle or bearing 5 is scoop-shaped,

with the tubular slots 6 in its flat sides opposite and in alignment.The leaf 1 is set down in the cradle 5, and the pintles 2 take intoslots 6. Then the cradle 5 has its sides swaged into parallel position,as shown in Fig. G.

The pin 8 is placed fast in sleeve 4, and the cradle 5 is fixed downupon the bar 7 by one of its closed faces, so that the other closed facelooks in the direction of the body of the pin 8, which bears upon theedge of the cradle, in

order to gain a certain resiliency when the pin Sis fastened orunfastened by thesafety-hook 9.

In the modification ofFig. I the cradle 5 is in the f0 rm of a flatstrip bent somewhat U shaped, with its bottom or cross piece securedupon the bar 7, and the free ends slotted at 6 to receive the 7 5pintles 20f the leaf 1, which is here somewhat altered in shape, havingthe acute corner 10 resting upon bar 7, to give the required resiliencyto the pin 8 in its operations.

In Figs.J and K, I show a modified form of my peculiar leaf 1. The blank11 is struck up, as shown, from flat stock, with the pintles 2, and isswaged into the form of Fig. J, where the one piece forms the leaf 1,with its pintles 2 and sleeve 4. It is obvious that the leaf 1 turnsfreely upon its pintles 2 in their bearings in slots 6 of the cradle 5,and can only be displaced from operative position by the cradle 5becoming badly sprained in its slotted sides, whereby the pintles 2would become disengaged from their slots 6. Thus my hinge-joint forms avery durable and simple joint, and works with efficieney.

There may be various modifications made in the parts of my devicewithout a substanbar, and the bar fitted tightly into a perfora- 10ction in the leaf or the leaf may be made flat and imperforate and havethe pintles soldered thereon, as desired.

having a stop-piece upon the attaching-face thereof, substantially asherein described.

2. The combination, with asheet-inetal cradle or bearing having lateralslots therein, of a leaf having lateral pintles and the integralstop-piece, substantially as described.

3. The combination, with a cradle or bearing provided with lateralslots, of a leaf provided with lateral pintles and a stop-piece and asleeve mounted upon said leaf and abutting against said stop,substantially as described.

4. The combination, with the cradle or bearing having the lateral slotstherein, of the leaf 20 provided with the pintles 2 and having the stop3 mounted thereon, substantially as described.

5. The combination, with the cradle or bearing 5, provided with theslots 6, of the leaf 1, having the pintles 2 and the stop 3, andprovided with the sleeve 4, substantially as described.

In Witness whereof I have hereunto set my hand.
